Title: Intercommunication systems
IPC: H04M11/02
Filed: 1974-08-09
Abstract: 1473370 Intercommunication systems LICENTIA PATENT-VERWALTUNGS GmbH 9 Aug 1974 [20 Aug 1973] 35376/74 Heading H4K The stations of a wired intercommunications system are connected to a transceiver for communication with a plurality of portable telephone units. In a first arrangement, Fig. 1, the stations are interconnected by a call wire 3, on which are transmitted multifrequency tone calling signals, and a plurality of speech wires 4-6, a called station responding to the receipt of an associated call signal by searching for a free speech wire as identified by the potential thereon i.e. 24 v. When a free speech wire is seized by a called station the potential drops from 24 v. to 10 v. and the calling station seizes the wire carrying 10 v. to further drop the voltage to 3 v. thereby busying the wire. For communication with a mobile subscriber, e.g. a person carrying a portable transceiver unit, a calling multifrequency tone signal identifying the portable unit is transmitted on a separate wire 7 to a transmitter 10. A connection is then set up using wire 7 as the speech path between the calling station and the stationary transceiver 8-10. For a call from a portable unit, it may be arranged for the transmitter 10 to be switched on either automatically or by operation of a switch at the called station. In a second embodiment (Fig. 2, not shown) the transceiver 8-10 is coupled to wires 3-6 in the same manner as the wired stations of Fig. 1, and wire 7 is not provided. Connections are then set up as for connections between two wired stations as already described except that the multifrequency calling tones associated with portable units are accompanied by a tone which identifies the called unit as being a portable unit. With such an arrangement the same basic calling tone can be used for both a portable unit and a wired station. It is then possible for a person having both a portable unit and a wired station with the same basic number, to plug his transceiver into a unit at his wired station, such that the decoder of his portable transceiver acts as the decoder for the wired station. Hence the subscriber is contactable by the wired system when the portable unit is plugged-in at his station and by radio when he leaves his wired station, the changeover being effected by a switch which is operated when the portable unit is plugged-in or removed.
